Getting a glimpse under the surface of any body of water is always a treat but in Iceland, this is truly an otherworldly experience. Snorkelling or diving in these parts may sound chilly but with the right equipment and professional guides, it can be both enchanting and meditatively relaxing.
If you plan on snorkelling anywhere in the world, we would put the Silfra fissure in Þingvellir National Park at the top of that list. It’s a waterfilled rift between the North American and Eurasian tectonic plates and one of Thingvellir’s deepest and largest fissures. What makes it all the more special is that the water of Silfra is originally meltwater from Langjökull glacier that has been filtered through lava for up to 100 years, making it extremely pure and therefore, very clear. The visibility here is quite unreal and if you’re not into geology now, you will be after this close encounter to Earth’s core functions.
